Donald F. Greene

Among those on the plane that crashed in Pennsylvania after passengers discussed attacking their hijackers, Donald Greene, 52, was himself a licensed pilot, his sister-in-law said. He also was CEO and first vice president of an aviation company called Safe-Flight in White Plains, N.Y.

"If anyone needed help, Don jumped right in," sister-in-law Cecilia Rhoda said. He was the same at home. He coached soccer teams for both of his children. His youngest is 6.
